This study questions key postcolonial notions from a French Caribbean perspective. Focusing on Édouard Glissant and Patrick Chamoiseau, this article argues that while trying to capture the cross-cultural relations that are at the core of creolization, the authors insist on difference which can be traced in their reference to ethnography. The first part consists of a critical assessment of the uses of the Caribbean within a postcolonial context based on Glissant. The second part analyses how Chamoiseau inscribes ethnography in his novels to explore the experience of living creolization and needing to express one’s difference.
